The recall may hurt Symbion Inc, maker of the Jarvik-7, but it won't end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power source created a passage for infection (感染). Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient's chest. The first sample products aren't expected for another 10 or 20 years. But some people are already worrying that they'll work - and that America's overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. If such expenditures (開支) cut into funding for more basic care, the net effect could actually be a decline in the nation's health.
注：1.recall 取消，re 有“向后”含義
2.看到Symbion Inc.就把32題標(biāo)在這里；看到new devices就把33題標(biāo)在這里。
3.external 外部的，passage 通道
4.work 可行、有效，they 指代前文 the first sample product
5.providing 引導(dǎo)現(xiàn)在分詞做狀語
指代題做法：1.將代詞所在句代詞之前部分的名詞以及代詞之前句子的名詞劃出
2.根據(jù)單復(fù)數(shù)縮小范圍
3.注意結(jié)合動詞判斷所指代為人、事或物
